SPEOIFICATI6N forming part of Letters Patent No. 659,601, dated October, 9, IQQO,

Application filed May 29, 1899, Saris-1N0. 718,696. (N d -l To a whom it mag concern.-

llc it known that I, LORENZO D. BENNER, a citizen of the United Slates,residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Paper Bags; and I do hereby declare that the following is a full, clear,

and exact description of the invention, which 7 will enable others skilled in the artto .posite end equal which it appertains to make and use the same.

This invention has reference to the formation and separation of tubular bag-blanks preparatory to the formation of the bottoms therefor and separating the bag into suitable lengths so that the necessary creases may be imparted to the bag at its bottom, which will cause the bag when distended to be filled to assume a rectangular form.

More particularly my invention relates to a bag-blank arranged to be severed from an endless web of paper or other suitable material that is folded on longitudinal lines by suitable means into bellows-sided tubular form, as is shown in the drawings, and where in the formation of the bottom a waste of paper will reduced to a minimum.

The invention consists, essentially, in severing bag length from an endless web of paper, so as to leave at one end extended bellows-sided portions and at the opposite end shortened bellows sides equal to the extended end at the opposite'end, forming the sides of the bag length, to have extended side portions opposite to the protruding bellows-sided extensions and with shortened sides at its opto theside extensions at the opposite end of the bag, length, the object being severing the length from a web of paper that from each succeeding bag length the separation will be such as to leave protruding or end extensions of the bellows sides at one end and at the opposite end endextensions of the sides of the bag.

In the drawings I have illustrated the various steps of the method of producing this bag.

Figure l is a plan view showing the manner of cutting the tube or forming the same into convenient lengths. Fig. 2 a view showing the man-nor of cutting the corners of op posi teend.

the bellows folds so as to form the sectional bottom portions. Fig. 3 is a the process wherein the bellows side-extensions are folded back toward the center and having matching end portions centrally disposed. bottom portion of the bag as itappears when the bag is openor filled.

The bag-blank A, previous to the formation of the bottom, is suitably cut from a strip in such a manner as to leave at one end the truding end extensions act of the bellows folds and at the opposite end the side extensions at, equal in length over the bellows sides to the protruding bellows side extensions at the In the process of completing the bag after the same has been severed in length, as described, the same iscreased on the line a to aid in making the preliminary folds, and incisions or cuts are made in the corners of the inward bellows folds to a suitable point on their lengths, as at l) b, which will separate the sides from the bellows folds, as is shown in Fig. 2, the abutting extensions a a, thus prod uced having the advantage of bracing the bottom of the bag.- The next step in the operation is to return the bellows side extensions a a, inwardly folding them on parallel lines with the edges of the bag, the remainder of their lengths being such as to cause them to have the centrally-disposed abutting ends 0 0 when folded down, which is clearly seen in Fig. 3, and then by folding overthe side extensions 0 a, formed by the incisions made in the corners of the bellows sides on parallel lines with the lengths of the bellows folds extensions as they are laid down, the extensions 0 a will have overlapping portions a short distance from the center of the bottom on opposite sides. Thus it will be seen that by the preliminary step of so cutting the baglength as to leave protruding end extensions am enabled when separating the sides fro'iir the bellows folds by making suitable incisib'ns, as herein set forth, to form a Fig. 4 is a perspective View of the prourther step in I i single bottom by the matching ends a or and p Letters Paltenf,

Having thus fully described my invention,

what I claim as newnmd d 'The herein,- 5 hiank,havingthe esire to secure by of the United States, isdescribed bellows sided hagbeliows-sided extensions a,

and the oppositely-protruding side extensions a, the crease on the cuts in the corners of to a point as at b b, forinin line a, the incisions or the inward hellows folds g the overlapping extensions c', c, and the abnfti V a, a, in the helinwsnnd side portions; for the pur ose described.
